74F673A
16-Bit Serial-In, Serial/Parallel-Out Shift Register
General Description
The 74F673A contains a 16-bit serial-in, serial-out shift
register and a 16-bit Parallel-Out storage register. A single
pin serves either as an input for serial entry or as a 3-
STATE serial output. In the Serial-Out mode, the data recir-
culates in the shift register. By means of a separate clock,
the contents of the shift register are transferred to the stor-
age register for parallel outputting. The contents of the stor-
age register can also be parallel loaded back into the shift
register. A HIGH signal on the Chip Select input prevents
both shifting and parallel transfer. The storage register may
be cleared via STMR.
